• Helping to build out a training dataset for a methane detection model in order to develop a multi-satellite monitoring system.

West Virginia, United States

Analyzed aerial infrared data to detect and quantify methane emissions on oil and gas infrastructure using tools such as QGIS, PostgreSQL, Python, AWS, and GitHub. Increased efficiency across company with following projects.• Co-led team to create a Juptyer notebook-run tool to automate end-of-survey reports (maps, graphs, and tables with built-in quality checks against a PostreSQL database) for customers, saving hours of manual labor per report. Wrote the requirements specification and managed assignments using Asana and GitHub. Enforced standards for Python style, code reviews, and documentation.• Improved the algorithm for estimating wind directions from methane plumes in our imagery in the tricky low-wind speed and large emission parameter spaces.• Automated a Python-based tool for retrieving flight paths with Spire Aviation API and mapping them in QGIS. Developed an algorithm for detecting and removing “deadhead” so could quickly produce clean survey footprint maps for potential customers, saving on average an hour of manual work per map.• Wrote the analysis team’s Python and GitHub guides for style and best practices.--------------------------------

Greenbelt, Maryland, United States

• Constructed a website with a Mojolicious framework and PostgreSQL database for visualizing geometric characterization products for the GOES-R series of Earth-observing satellites.• Wrote Python-based data visualization tool for GOES-R anomaly investigations. Used tool to quantify how many geolocation referencing chips get lost in the infrared bands in the summer months.• Performed weekly monitoring of geometric characterization metrics.--------------------------------

Greenbelt, Maryland, United States

• Software developer and analyst for the NASA earth mission ICESat-2 (Ice, Cloud, and land Elevation Satellite).• Developed and maintained PostgreSQL database of the metadata for the daily low-level data products of ICESat-2.• Wrote Python software to perform quality assurance on the level-1b products of ICESat-2; discovered and brought to resolution over 400 issues.• Computed and documented four radiometric calibration products for ICESat-2's lidar instrument.• Contributed corrections and content to the level-1b Algorithm Theoretical Basis Document: https://icesat-2.gsfc.nasa.gov/sites/default/files/page_files/ICESat2_ATL02_ATBD_r006.pdf• Presented two posters on ICESat-2 work at the annual American Geophysical Union meeting.--------------------------------

Baltimore, Maryland, United States

• Developed verification tests for the James Webb Space Telescope calibration pipeline.• Member of solar system working group for James Webb Space Telescope. Wrote user documentation and produced spectra of solar system targets for the Exposure Time Calculator. Supported workshops for JWST solar system observers.--------------------------------

Baltimore, Md

• Performed daily quality control of the science images of the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) and investigated anomalies as needed.• Principle investigator of the charge transfer efficiency, gain, linearity, and photometric stability for the HST WFC3 ultraviolet and infrared detectors. Developed Python analysis and metrics tools, automated software, built databases, and published technical reports.• Deputy lead of team that managed a SQL database of WFC3 metadata.• Improved the charge transfer efficiency algorithm and designed and automated a processing pipeline, producing a large increase in speed and reproducibility from the manual workflow it replaced.• Wrote tutorials, mentored junior team members, and trained new hires.• Lead of the HST WFC3 instrument’s help desk. Answered and funneled questions to team members• Wrote and edited user documentation.• Gave seven poster presentations at professional meetings for users of HST and JWST.--------------------------------Publications:C.M.
